About the Dongle PCB

Dongle is an open source ESP32 PCB design by Bilaikra2014, published on GitHub. It is a 2-layer board measuring 34.9 × 18.3 mm, with 15 components from 12 distinct parts.

Its main chip is the ESP32-S3-MINI-1-N8, from the ESP32 family. Other key parts include the USBLC6-2P6. By type, the board carries 5 capacitors, 3 resistors, 2 ICs, 2 switches, 1 connector and 1 diode.

It belongs with the keyboards and iot & wireless designs in this gallery.

Ce projet a pour objectif la conception et la fabrication d'un clavier mécanique (Filaire USB-C / Sans-fil). Le système repose sur un écosystème ESP32 permettant une communication rapide et personnalisée. Ce projet est une première version de test, une autre version pourrait être conçue dans le but de rechercher encore plus de perfomance en utilisant des composants plus adaptés.

Dongle: common questions

What microcontroller does the Dongle use?

The Dongle is built around the ESP32-S3-MINI-1-N8, from the ESP32 family.

How big is the Dongle PCB?

The Dongle measures 34.9 × 18.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Dongle?

15 components, from 12 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Dongle design files?

From the Bilaikra2014/Keyboard repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Dongle design in my own project?

The repository has no license, so all rights stay with Bilaikra2014. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Dongle without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
